World Power Plug Types Meaning
Packing for Europe, the UK, Japan, or Australia? Decode Type A, B, C, G, and I wall sockets, 110V vs 230V voltage traps, and adapter safety.
Crucial Warning: Adapter vs Voltage Converter (Don’t Fry Hair Dryers!)
A cheap plastic travel adapter ONLY changes the pin shape—it does NOT change the voltage! Modern laptop and phone chargers are dual-voltage (100V–240V) and work worldwide safely. However, standard American hair dryers, curlers, and blenders are built strictly for 110V; plugging them into a 230V European Type C or UK Type G outlet with a basic adapter will instantly catch fire or blow a fuse.
